How to Choose the Perfect CPU for RX 6800?

Understanding CPU Bottlenecks

A CPU bottleneck occurs when your processor can’t provide data to your RX 6800 fast enough, limiting your frame rates. At 1080p, this is more likely to happen because the GPU isn’t being pushed to its limits.

Think of it like this: your CPU prepares the frames, and your GPU renders them. If the CPU can’t prepare frames fast enough, your powerful RX 6800 will sit idle waiting for work.

The bottleneck threshold varies by game, but generally, you want a CPU that can maintain at least 100 FPS in the games you play to avoid limiting your RX 6800.

Resolution Matters

Your target gaming resolution significantly impacts CPU requirements:

• 1080p: Most CPU-demanding. You need a powerful processor to prevent bottlenecking.
• 1440p: The sweet spot for RX 6800. CPU requirements are more relaxed.
• 4K: GPU becomes the bottleneck. Even mid-range CPUs work well.

For 1080p gaming, I recommend at least a Ryzen 5 5600X or Intel i5-12400F. At 1440p, you can get away with less powerful CPUs, but having headroom ensures smooth performance in CPU-intensive titles.
